Purchased a 2013 EL

It’s got 6 batteries under the seat and aluminum bed. I’ve got 72 volts up to the main contactor, nothing at controller and motor. I’ve got no display with key on and master on. The GEM has signs everywhere that says touch to start. The only thing that currently works is the buzzer with emergency break off. Any suggestions! The controller is currently not bolted to the six screws. 72volts packs a punch. lol. I got the display working by unplugging the green wire coming out of quiq charger, I also noticed that the dc to dc converter is integrated into the charger!
